Hello, I wish to use script which perform some simple calculations on NetCDF variables and store result values as a matrix. Author claims that script needs 64-bit MATLAB version installed on Linux machine. Unfortunately, although I have 64-bit machine, under Linux I have access to 32-bit MATLAB only. Following warning is returned: Error using class The CLASS function must be called from a class constructor. Could you tell me: - what (in terms of syntax, available functions, methods, objects) are the differences between 64-bit and 32-bit MATLAB? - is it possible to workaround such problems in 32-bit MATLAB? - will it be possible to run mentioned script in 64-bit MATLAB under Windows?

I'd suggest that trying to figure out a complete list of differences might be a waste of time. After all, most differences would be of no meaning here. Anyway, a large part of the difference will be simply the ability to use larger arrays, a larger address space, UNLESS the issue is really that you need to use an up to date version. The error message suggests that is really the issue. What MATLAB release is your 32 bit installation? So if it is as I suspect, that it is a release issue, there are MANY changes between releases that MAY be pertinent, but again, too many for an exhaustive list here and too many changes that would be totally unimportant to you.

John, thank for your response. As I can see, mentioned script "Requires 64-bit Matlab, version 2009a". I have 32-bit, R2012a Student version.

That error message suggests that the problem is not a version or 32/64 bit difference, but that some file is not in the correct location. But since you have release R2012a, most or all of the functions on this page should be present in your installation. http://www.mathworks.com/help/matlab/ref/netcdf.html Find the version of that page in your installation's documentation for a list of exactly which of these functions are available (some may have been introduced in release R2012b or later.) If you're using those scripts to read in the NetCDF files, try using the functions provided in MATLAB instead. -- Steve Lord slord@mathworks.com To contact Technical Support use the Contact Us link on http://www.mathworks.com

Hi, I had to move to a different PC which happened to have Windows Vista 64-bit and MATLAB 64-bit rather than XP 32-bit. (MATLAB R209b in both cases.) I was surprised to see my simulation results change slightly. Does this surprise anyone else? I checked that I had moved the same model and input data files correctly but obviously it is always possible that I've done something stupid! Large parts of the model use integer or fi math and most of the floating point is single precision. Any comments greatly appreciated, Matt Hi Matt, Could you provide some code snippets ...

Right now we have Matlab R2007a running on a 32 bit Linux server, which is accessed from our 32 bit workstations. Next week we will be adding a few workstations with 64 bit CPU's, so I have a couple of questions: 1) Can I install the 64 bit version of Matlab on a 32 bit server and run it from a 64 bit workstation? If yes, 2) Can I install both 32 and 64 bit versions of Matlab on the same server, and have the license manager handle both? Or do I need two license managers running? Detailed steps would be greatly appreciated. On Apr 10, 4:22 pm, "Joachim Stahl" <s...@hotmai...

Hi, I've some mex code(compiled by somebody else on 32-bit machines) but I currently have a 64-bit version of Matlab installed on 64-bit ubuntu. I saw this suggestion from somebody- http://www.mathworks.cn/matlabcentral/newsreader/view_thread/100595 "The fix (since you can't recompile the .mex files) is to run the x86 version of Matlab, which you can install alongside the native x86_64 version.

Has anyone had any experience running the 64-bit beta version of MatLab in a Terminal Server environment? Any problems other than those listed in the "known issues"? We are considering a Terminal Server environment but we haven't decided to if we will go with Windows 2003 Server 32-bit or 64-bit. We would like to use more than 4 gb of RAM on the server (which means either 32-bit Enterprise Edition or 64-bit). If we use 32-bit EE with more than 4 gb of RAM on a multiple CPU server, will users be able to use more than 4 gb RAM with multiple sessions or is MatLab still restricted ...

I have a 64 bit machine with an (older) 32 bit version of matlab installed on it. I am wondering if it is possible to execute 64-bit mex files (compiled on a 64-bit machine).
